Very poor service Afrihost

I have never ever seen such a poor service in my whole life. These guys are the worst especially the accounts department. They debited me twice for a router on Saturday the 4th of November 2023, and in their system it still says "pending payment" today (10 November 2023). They promised to credit me the money they debited twice but still i havent receieved anything. woke up this morning another debit order. they dont communicate anything they just say they will fix it and nothing. I have emailed them twice and they have not responded. i have whatsapp them countless times and they keep say "sorry for inconvience" I regret taking this fibre from Afrihost. I would like to request help on how to get my money back and also advice on which fibre next works provide a better service. thank you.
